The Santa Maria della Pietà complex used to serve as a leper hospital, erected at the time of the Sforza rule in the middle of the 15th century. Inside the austere brick building there is a large hall (originally employed to house the sick), which was raised with a barrel vault in the 18th century and given a wrought iron balcony, which allowed medical checks to be carried out. The hall leads to a quaint porticoed cloister, decorated in Lombard Renaissance style terracottas, attributed to artist Rinaldo De Stauris. The complex is currently civic property, and houses offices as well as cultural events.
